Why are chestnuts roasted with pebbles? Kuya Kim explains

Chestnuts are part of Christmas festivities all around the world, but why are they roasted with pebbles?

On Monday's "24 Oras," Kuya Kim said pebbles absorb the right kind of heat from the pan so chestnuts or castañas can get roasted evenly. Through this, the nuts retain its original taste and aroma.

From being rough on the outside, it becomes smooth and shiny because of the oil used to roast them.

Like other kinds of nuts, chestnuts' shells are also hard to remove. It can be eaten by cracking its shell by hand or by teeth.

Chestnuts have been a part of holidays for years. In fact, it's included in some songs such as "Sa Paskong Darating" and Nat King Cole's "The Christmas Song."

Meanwhile, a nutcracker soldier is also considered a Christmas icon globally. Like what it's called, their real purpose is to crack nuts with their mouths.
